Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If antenna reference points are not explicitly signaled, then signaling overhead is reduced, but positioning precision and inter-device communication reliability deteriorate
Solution Approach 1:
The patent applies preliminary action by pre-configuring antenna reference point information through higher layer signaling (RRC) before actual positioning or inter-device communication occurs. This allows the UE to have antenna reference point identifiers readily available when needed, eliminating the need for real-time signaling while maintaining positioning precision.
Solution Approach 2:
The patent introduces an intermediary mechanism by using higher layer signaling (RRC) as a mediator to transmit antenna reference point information. This intermediary layer handles the information transfer in advance, allowing the physical layer to operate with reduced signaling overhead while still accessing necessary antenna reference point data for precise positioning.
2Measurement precision
If antenna reference point information is signaled in real-time, then positioning precision is improved, but signaling overhead and latency increase
Solution Approach 1:
The patent resolves this contradiction by performing the signaling action in advance through higher layer RRC signaling. The antenna reference point information is configured before the actual positioning measurement or inter-device communication occurs, eliminating real-time signaling latency while maintaining positioning precision.
3Adaptability or versatility
If multiple antenna reference points are supported, then adaptability for different positioning scenarios is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing antenna reference point information into separate, independently configurable identifiers. Each antenna reference point can be individually configured and identified, allowing the system to support multiple positioning scenarios by selectively activating appropriate reference points without increasing overall device complexity.
Solution Approach 2:
The patent implements universality by creating a generalizable antenna reference point identification mechanism that can be applied across different positioning scenarios and inter-device communication contexts. The same RRC configuration framework serves multiple functions including positioning, beam management, and communication, reducing the need for scenario-specific implementations.
